Description

Technical Field

[0001] This utility model relates to the field of polyethylene synthetic fiber processing equipment, and in particular to a rotary adjustable polyethylene synthetic fiber drying device. Background Technology

[0002] In order to remove residual solvent from the surface of polyethylene synthetic fibers, the polyethylene synthetic fibers need to be cleaned and dried during the production process.

[0003] The production volume of polyethylene synthetic fibers is relatively large, with hundreds or even thousands of polyethylene synthetic fibers being simultaneously output, washed, dried, and wound up, requiring high drying efficiency. In order to reduce the size of the production equipment, the drying of polyethylene synthetic fibers is usually carried out in bundles. Hot air has difficulty reaching the polyethylene synthetic fibers inside the fiber bundle. Even if the fibers are bundled, each bundle still contains hundreds of polyethylene synthetic fibers, and it is still difficult to ensure the drying effect of the fibers on the leeward side of the fiber bundle. Improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a rotary adjustable polyethylene synthetic fiber drying device for drying polyethylene synthetic fibers and improving the drying effect.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A rotary adjustable polyethylene synthetic fiber drying device includes: a drying chamber, a first guide roller, a second guide roller, a rotary drive roller, an air distribution box, a fan, and a heating chamber. The first and second guide rollers are horizontally arranged in the drying chamber with a back-to-back gap. The rotary drive roller is axially reciprocatingly arranged in the drying chamber and located between the first and second guide rollers. The first and second guide rollers are respectively provided with spaced ring plates, and adjacent ring plates form a bundle-splitting channel corresponding to the polyethylene synthetic fiber. The polyethylene synthetic fiber is bundled and transported through the bundle-splitting channels on the first and second guide rollers. The air distribution box is arranged in the drying chamber and located below the rotary drive roller. The air distribution box is provided with an upward-pointing air nozzle. A pipe is provided between the air outlet of the heating chamber and the air distribution box. The air outlet of the fan is connected to the air inlet of the heating chamber.

[0007] The bottom position of the rotating drive roller is lower than the top position of the first guide roller and the second guide roller.

[0008] The jet nozzles are distributed at intervals along the path of the polyethylene synthetic fibers between the first guide roller and the second guide roller.

[0009] The heating box is equipped with an electric heating wire.

[0010] The drying chamber is equipped with a slide rail located above the rotating drive roller, and a slider located on the slide rail is provided on the top of the rotating drive roller.

[0011] The drying oven has a motor located above one side of the slider at the top. A turntable is mounted on the motor shaft. A first pin is eccentrically mounted on the turntable. A second pin, corresponding to the first pin, is mounted on one side of the slider. A connecting rod is provided between the first pin and the second pin.

[0012] The drying oven is provided with a clearance groove corresponding to the connecting rod.

[0013] The connecting rod is provided with bearings at both ends.

[0014] The beneficial effects of this utility model are as follows: A rotary adjustable polyethylene synthetic fiber drying device can transport polyethylene synthetic fibers in bundles through a bundle-splitting channel, reducing the pressure of the drying work. When passing through the rotary drive roller, the fiber bundle is driven to rotate and reciprocate by the axial reciprocating motion of the rotary drive roller, continuously adjusting the angle of the air-receiving surface to achieve 360° air-receiving drying and ensure the drying effect.

[0016] Figure 2 yes Figure 1 Left view of the first guide roller. Detailed Implementation

[0017] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0018] like Figure 1 The rotary adjustable polyethylene synthetic fiber drying device shown is used for bundling and drying polyethylene synthetic fibers 9. It includes: a drying chamber 1, a first guide roller 11, a second guide roller 12, a rotary drive roller 8, an air distribution box 5, a fan 2, and a heating chamber 3. The first guide roller 11 and the second guide roller 12 are arranged horizontally and at intervals in the drying chamber 1 to guide the polyethylene synthetic fibers 9. The polyethylene synthetic fibers 9 are pulled and wound by the winding equipment at the end of the production line to ensure tension during the drying process.

[0019] Annular plates 10 are respectively spaced apart on the first guide roller 11 and the second guide roller 12, and a bundle-splitting channel 20 corresponding to the polyethylene synthetic fiber 9 is formed between adjacent annular plates 10. The polyethylene synthetic fiber is bundled and transported through the bundle-splitting channel 20 on the first guide roller 11 and the second guide roller 12. Figure 2As shown, the polyethylene synthetic fibers are divided into 5 bundles for separate transport. Each fiber bundle contains about 100 polyethylene synthetic fibers, which reduces mutual shading and lowers the pressure of the drying process.

[0020] The rotating drive roller 8 is axially reciprocatingly arranged in the drying chamber 1 and located between the first guide roller 11 and the second guide roller 12. In this embodiment, the bottom position of the rotating drive roller 8 is lower than the top position of the first guide roller 11 and the second guide roller 12 to tension and further flatten the fiber bundle.

[0021] In addition, a rubber sleeve is provided on the surface of the rotating drive roller 8. The rubber sleeve contacts the fiber bundle. When the rotating drive roller 8 moves axially, it can drive the polyethylene synthetic fiber to rotate repeatedly, continuously adjusting the angle of the wind-receiving surface of the polyethylene synthetic fiber 9 to achieve 360° wind-receiving drying and ensure the drying effect.

[0022] A slide rail 14 is provided in the drying chamber 1 above the rotating drive roller 8. A slider 13 is provided on the top of the rotating drive roller 8 on the slide rail 14 to guide the movement of the rotating drive roller 8 and avoid skewing.

[0023] like Figure 1 As shown, a motor 15 is provided on the top of the drying oven 1, located above the longitudinal side of the slider 13. A turntable 16 is provided on the rotating shaft of the motor 15, and a first pin 17 is eccentrically provided on the turntable 16. The motor 15 drives the first pin 17 to rotate eccentrically.

[0024] A second pin 6 corresponding to the first pin 17 is provided on one side of the slider 13. A connecting rod 18 is provided between the first pin 17 and the second pin 6. When the first pin 17 rotates eccentrically, the second pin 6 is pushed and pulled through the inclined connecting rod 18, which drives the slider 13 to reciprocate linear motion.

[0025] In this embodiment, the drying chamber 1 is provided with a clearance groove 19 corresponding to the connecting rod 18, which does not affect the movement of the connecting rod 18. Bearings are respectively provided at both ends of the connecting rod 18, and the connecting rod 18 is movably connected to the first pin 17 and the second pin 6 through the bearings.

[0026] like Figure 1 As shown, the air distribution box 5 is located in the drying chamber 1 and below the rotating drive roller 8, that is, below the path of the polyethylene synthetic fiber 9. The air distribution box 5 is equipped with upward-pointing air nozzles 7, which are spaced apart along the path of the polyethylene synthetic fiber 9 between the first guide roller 11 and the second guide roller 12. Hot air is continuously sprayed onto the fiber bundle through multiple air nozzles 7, and in conjunction with the tumbling of the fiber bundle, 360° rapid drying is achieved.

[0027] A pipe 4 is provided between the air outlet of the heating chamber 3 and the air distribution box 5. The air outlet of the fan 2 is connected to the air inlet of the heating chamber 3. The fan 2 sends external airflow into the heating chamber 3, heats it, and then sends it to the air distribution box 5 through the pipe 4. In this embodiment, the heating chamber 3 is equipped with an electric heating wire, which can be automatically controlled by a temperature switch to ensure that the temperature of the hot air in the pipe 4 is within a set range, thus ensuring drying efficiency without damaging the polyethylene synthetic fiber 9.
